Lady with a bit of an accent called... kind of hard to understand, but I think she said she was with a company called MPG.  Asked if we accepted credit cards.  We do.  Then she immediately said we needed to upgrade to an EMV chip reader.  I already have one.  Undeterred, she then said, "That's OK... I want to give you better rates...", and then quoted a bunch of numbers.  Then she wanted our merchant #.  This all happened within about 20 seconds, so she was very efficient.  But that's when I knew it was time to end the call.
